To all whom it may concern:

Be it known that l, PARK E. WELTON, a a

citizen of the United States, residing at Cuyahoga Falls, in the county of Summ tand State of Ohio, have invented a certain new end useful Improvement in Tire-Wrapping Machines, of which the following is a full, clear, and exact description.

This invention relates to improvements in the kind of machines organized to spirally wrap a narrow strip of paper or fabricaround an annulus, such, for example, as a pneumatic tire casing.

One object of the invention is to produce a cheaper machine for thispurpose than has heretofore been known, and one which will run with less noise, and with great-speed.

Another object of the invention is to so construct such a machine that a cord Wlll he laid thereby between the wrapping and the annulus, extending circumferentially arpuucl the latter,the purpose of the cord being to rip the wrapping so that it rnayhe easily removed from the annulus.

Another ologect is to so organise a machine of this sort that it will pastefontothe spiral wrepnings s paper strip which extends cir cuniferentielly around the annulus,- -the purpose of said s rip heme; to protect the wrapping from injury.

And finally, the object is to so organize such a machine that the unwrappeol annulus may be quickly putinto the machine and the wrapped annulus quickly taken therefrom,

The invention consists in the construction and combination of parts by which these ends are attained substantially as shown in' the drawings, end hereinafter described and definitely pointed out in the appended claims In the drawings, Figure 1 1s a frontelevation of a machine embodying the invention ancla sectional VIEW or a tire casing part of the machine; Fig. 4 is a View look-' 'ing down upon that part of the shuttle 7 while supported in thernachine and while being wrapped; Fig. 2 s a V ew. from the right side ofFig. 1; Fig. 3 IS. a detached view or the rotary shuttle which forms a which forms the bottom of Fig. 8; Fig. 5 is 'a-sectionel view on line 5-5 of Fig. l; and

resents an open topped circular housing,

rollers extends down into the housing. in

the form of a loop and in this loop the ennular shuttle 20 is hung. This belt after it leaves the shuttle passes over the roller 40, thence between two tension rolls 42, 43, under a driving roll is over a guide roll -15, and under two guide rolls 46 and 47, then up to and over roll 41, and down into the housing to form the shuttle supporting loop. The driving roll 44- is fixed to-a driven shaft 48 which carries a gear 49 adapted to be engggagecl by e pinion 50 fixed to the main driving shaft 51 of the machine.

in the periphery of the annular shuttle there is acircurnferential groove 20*between the two flanges 20*, 20". This shuttle is of such diameter that when hung" in the loop of the belt as'stated, its edges project between and therefore overlap the edges of the front and rear plates of the housing,

substantially as shown, which insures that. v the shuttle shall have no substantial movement in the direction of its axis ofrotation. It is to be noted that the two belt rolls 40 and ll are located above the axis of rotation of the shuttle and overhang the shuttle to an extent such as to substantially prevent any upward movement thereof.

The annular shuttle 20 is formed in partof an are shaped gate 25 which is adapted to fill an opening cut in the shuttle proper, and

being below the axis about whieh t may be employed, but the latch show is a little rotatable shaft which between it ends is half cut away. The end of the has a seen-circular recess. This leteh melbe turned so as to project into this recess, and therefore hitch the gate, or not to pro-- ject into it at all and thereby allow the gate to be opened.

This shuttle has o o osite the ote en inwardly directed flange 20 on "fi'il .rh certain parts now to be described are supggorted. reel 21 is rotatably inoioited on arbor :21 fixed to this flange, which arbor is parallel with the axis aboutwhich the shuttle turns. On this reel 2. long narrow strip olf 1;. her or fabric P may be wound.

From this reel the paper passes through an edge-folder "32 which is fixed to said flange and by which one edge of the strip P is turned. This etlge'iolder is, 2067' so, of familiar io" therefore need not be further ezqil T he paper with its edge turned over by this folder posses between two rolls 23, 2 L thence to the m'inulus on which it is to be wound. The roll may be merited on a fixed stud 23, but the roll 2 2 preferably mount-ed in the forked end of a swinging arm which is pivoted to the flange 20", and is under the influence of a spring 537 acting to move the swinging roll 2 against the paper which is passing between rolls 24; and 23. This spring actuated roll 2%: in eooperation with the roll 23 sets as a tension device, and also flattens down the turned over edge of the eper strip.

The annulus to "so wrapped supported while being wrapped, is slowly turned in order that the Wilt "ling may be laid spirally, by two pairs of i aged rollers 33, 3%, vim, one pair carried by a. shaft 310 which extends horizontally in front oi the housing, and the other of 'yhieh extends horizontally behind the housing be turns The two rollers 33, 33, on the shztf 30 have a driving connection with seirl shaft; but the two rollers 34-, 3 on the iii-oer shaft may be loosely rotatable thereon. Ti. J0 springs 36, 37, act on the sleeves of em. to move them toward. one soother. casing rests on the cylindrical ports of seid sleeves, and the flanges 38 of sue-h sleeves engage the sides of the tire easing and set to press the two edges thereof together. As the paper strip is carried erased the tire casing by the shuttle, the shaft 3G is slowly turned and thereby the tire ing will be caused lJOaittlVtlliCr": slowly from front to rear. Sinoe the shuttle rotating at the same time, the psper strip will; be

wrapped spirelly about the tire casing be tween the two pairs of flanged rolls end therefore upon that ert oi the tire eesiog wlose edges are bemgpressed together. when, therefore, the wrapped tire oesiiig;

but passing and oft oi? the rear id slightly, end theieb salt; but as state/chit is desireble'to ripping cord oireimifereiitielly lip-01 the tire oesmg beneeth the peper wrapping;

and it is also desirable to paste a oroteeting strip of paper oireuniferentielly aroused the tire and on the outer surface of the spiral wrapping thereon. In order to so let the eord C on arm oil is pivoted on "tortioel 55 to the housing above the tire easing; and when in won: 1g position is one extends from its pivotal g; int horizontally beyond the center of rotation of the shuttle.

A forked arm is pii otslly mounted upon this red and it extends forward and downward therefrom. l: I its outer end concave roll 52" is rotatably mounted. it oord spool 53 is also supported on the rod 50 and guide eye 55 is also carried on this arm. goes from this spool, thrzmggh guide eye, and thence doi 'v'nwm-d.under this roll on the t'roht side thereof, the end this cord be mg in some suitable way eonoeeted with the tire cesiiw.

The weight of the roll end the arm in which it is mounted i sy sullieieiitly greet to hold the roll clown upon the surfer-Ce of the unwrapped tire casing. Therefore, the tire casing is turned, the cord will be laid on that port of its surifgioe which i close to and approaching the point at which spiral paper wrapping will be e iplied thereto.

A latch 50, which shown is dotted lines is. Fig. 1, they be carried by this rod, and thereby the rod may be held in operative position described. This latch is simply e lengthwise throughtlie rod {50 end having at tin er in its end adopted to enter notch 5% iii the pivot pin on V! the influence of a spring B l tending to draw this finger into this notch; and it may be provided with a. projecting knob 5G by which the operator may press the ell in the con trery direetion end so nnieteb. the a in and permit it to be swung out of the way of tire casing which is beingput into or token trees the msohine.

-Another similar horizontel rod 78 is pin oted tothe rear side oil the housing and exhousing; toward another. A forked arm, 71 1s pivotelly hung upon it, and s roller 72 is mounted thereon 1:1 such position that it .llCl'l the arm is mounted. it may be under The oord lilfl tends horizontally {tom one side of the to this arm the upstanding standard 73 ere .may rest upon andbe turned by the wra ped part of the tire casing. There is also hxed in which a reel 7% is mounted on which is wound a strip S of paper tape which is gummed on its inner surface. To this standard is fixed a cup or' well 75 in which vater may be placed. Likewise these standards carry hearings in which three guide rolls 76, '7", 78, may be mounted, the guide roll 76 being so'mounted that it pro- ]ect's down into the water in said cup. When a wrapped part of the tire casing as it turns rearward comes under this roller the tape S whose gummed side has been moistened by contact with the roll 76 a it passes between said roll and roll '5'? p es over roll 78, and thence under roll "Z2 Toy which it is pressed down upon and thereby caused to adhere to the paper wrap; the tire casing. Thereafter, as the tn ing continues to rotate, this gummed and moistened paper strip willbe applied wrappings of the tire casin and 1;- down onto the same with su cient in means of the roller which, together wit supporting arm, may be 'suiiiciently heavy to etiect this result.
